D4-320 vs D4-300

Note: Some mini PCs may have weaker USB signal output, which can cause random interruptions during file read/write operations during data transmission. 

When this occurs, it is recommended to 1) use the rear USB ports of the computer, as they typically provide a more stable signal; 2) test the device on another known-good computer to rule out hardware issues on the original PC; and 3) use a 10Gbps USB-A/USB-C hub or splitter with a short 0.3m-0.5m cable to reduce signal loss.
